Infection / Bleeding
At egg collection a fine needle is passed through the vagina into the ovary to remove the eggs. There is a small risk at that time of causing bleeding from the ovary or introducing inflection into your pelvis. Great care is taken during the egg collection to minimise these risks and antibiotics are given. In practice, while a little bit of spotting of blood from the vagina is likely after the egg collection, significant bleeding is extremely rare. The chance of infection is less than one in one hundred.
